/*******************************************************************************
* ##########   关于Callback回调函数    ##########
*
* 回调函数 Callback functions 是系统程序开发中常用的一种机制。
*
* 在事件\消息驱动型的系统,我们会遇到以下情况:
* (1)系统并不知道应用程序要如何处理事件(如鼠标点击);
* (2)应用程序不知道何时会发生事件(如鼠标何时被点击)。
* 因此,应用程序定义好处理事件的函数,然后将这个函数的指针传递给操作系统,系统保存这个指针,
* 当事件发生时,系统通过指针调用这个函数。
*
* 因为很多情况下事件的发生都是硬件相关的,只有操作系统通过底层驱动才能获取硬件的IO情况。
* 现代操作系统的设计是不允许应用程序直接和硬件通讯的,必须全部由操作系统来进行管理。
*
* 回调函数并不神秘,基本原理就是函数指针。
* 在消息和事件处理、多线程、异步IO等情况下经常会使用到。
* 回调函数机制是“消息驱动型”程序的基本技术。
*
